Psychosocial factors associated with dementia, such as dementia worry and personal exposure to the illness, may influence the subjective perception of cognitive abilities. The present study examined the relationship of subjective memory concerns with dementia worry, as well as the moderating effects of dementia exposure. Community-dwelling adults aged 50 and above without diagnostic history of dementia or evidence of objective memory impairment completed self-report measures assessing subjective memory concerns, subjective memory decline, dementia worry, depressive symptoms, anxiety symptoms, and dementia exposure. Results revealed that higher subjective memory concerns were associated with greater dementia worry and depressive symptoms. Those with genetic dementia exposure reported higher dementia worry than those with nongenetic or no dementia exposure. Dementia exposure moderated the relationship of subjective memory concerns with dementia worry. These findings suggest that assessments of dementia worry and dementia exposure may be valuable in clinical evaluations of older adults presenting with memory concerns.
与痴呆相关的心理社会因素，如痴呆担忧和个人接触疾病，可能会影响对认知能力的主观感知。本研究考察了主观记忆担忧与痴呆担忧的关系，以及痴呆暴露的调节作用。没有痴呆诊断史或客观记忆障碍证据的 50 岁及以上的社区居住成年人完成了自我报告的测量，评估了主观记忆担忧、主观记忆下降、痴呆担忧、抑郁症状、焦虑症状和痴呆暴露。结果表明，较高的主观记忆担忧与较高的痴呆担忧和抑郁症状有关。有遗传痴呆暴露的人比无遗传或无痴呆暴露的人报告的痴呆担忧更高。痴呆暴露调节了主观记忆担忧与痴呆担忧的关系。这些发现表明，对痴呆担忧和痴呆暴露的评估可能对有记忆担忧的老年人的临床评估有价值。
